Part A

Lets consider the following java class.

class Student

{

String name;

public int grade; // grade between 0 and 100 (condition on Grade);

public void increment ()

{

grade ++;

}

public void decrement ()

{

// (condition on Grade)

grade - -;

}

public int getGrade()

{

return grade;

}

public void setGrade(int G)

{

// (condition on Grade)

grade = g;

}

Public addGrade(int x)

{

// (condition on Grade)

grade +=x;

}

void DisplayGrade()

{

System.out.println ("Grade = +grade);

}

}

Complete the following table

Main function	S1.grade	S2.grade
Public static void main() { Student s1= new Student(); s1.DisplayGrade() Student s2=new Student(); s1.grade = 59; s1.increment(); s1.increment(); s1.decrement(); s2.addGrade(10); s1.setGrade(55); s1.setgrade(s2.getGrade()); for(int i=1;i<=10:i++) s1.increment(); s2.decrement(); }

Version 2 Here we change grade from public to private public int grade;	S1.grade	S2.grade	Error or remark if any
public static void main() { Student s1= new Student(); Student s2=new Student(); s1.grade = 59; s1.setgrade(100); s1.incrementgrade(); s2.addgrade(s1.getGrade()); s1.setgrade(0); s1.decrement(); }
